Multiple alleles can be studied only in populations, not individuals. An example of multiple alleles would be blood type, each person has only one blood type, but a population has a many permutations.

∙ 9y agoIt is false that multiple alleles can be studied only in individuals. The truth is that they can also be studied when populations are available.

What are genes with three or more alleles called?
this makes no scientific sense. A gene (which determines a phenotypic trait) can only contain 2 alleles. However codominace allows for multiple alleles to be chosen from, but only 2 picked for a gene. Also, if multiple genes determine a phenotypic trait that's polygenic inheritance.
What do we call a description of an individuals alleles for a paticular gene?
That depends on the gene: some genes have only a few alleles, some genes have hundreds or even thousands of alleles.
What is it called when there are more than two alleles present in a population?
Chromosomes are made of tightly wound DNA and protein. Genes are found along the length of chromosomes. A gene is a segment of DNA that contains instructions for making a specific protein or proteins required by the body. Human beings have about 30,000 - 35,000 genes. We have two copies of each gene, but the copies can be slightly different. For example, the gene associated with cystic fibrosis has more than 1000 different variations. Different versions of the same gene are called its alleles, and everyone has two alleles for each gene. (Males have only one X chromosome, so they only have one copy of the genes located on the X chromosome.)
Is it true that recessive alleles are never present when dominant alleles are present?
No. They are present but not expressed (seen). Only the dominant alleles are expressed.
What is the significance of alleles?
They allow for a range of traits in the population. Mastering Bio.
Is this statement true or false multiple alleles can be studied only in individuals?

Is it true that multiple alleles can be studied only individuals?
Multiple alleles refers to there being more than two alleles for a particular trait. Incomplete dominance is when one allele does not completely mask another (as is usually the case in simple Mendelian inheritance) but instead the two traits are expressed equally. For example, if a red cow (RR) mates with a white cow (WW), their offspring will not be white and red, but a mixture of the two colors roan (RW). That is incomplete dominance.

How do multiple alleles control the trait?
In the case of multiple alleles, one trait is governed by more than two alleles. One example is the human ABO blood group. There are three alleles, A, B, and O. A person can, however, only inherit two of the three alleles.
True or false even though a gene has multiple alleles a person can carry only two of those alleles?
True
Is ABO blood group determined by multiple alleles?
* Type A alleles could be : IAIA or IAi* Type B alleles could be : IBIB or IBi* Type AB alleles : IAIB* Type O alleles : ii

That depends on the gene: some genes have only a few alleles, some genes have hundreds or even thousands of alleles.
What is the type of allele that only effect the phenotype in the homozygous chromosome?
Recessive. Dominant alleles are expressed in both homozygous and heterozygous individuals (DD or Dd), but recessive alleles are only expressed in homozygous individuals (dd).
What are multiple allels in biology?
Multiple alleles is a type of heredity in which one gene has more than two alleles. For example, in humans the gene for blood group has three alleles, A, B, and O. Even though there are three alleles in the population, a person can only inherit two alleles, one from his/her mother and one from his/her father.
For a gene that has multiple alleles more than 2 what is the maximum number of different allels a normal individual can have?
2. Even though there are multiple alleles for the same characteristic in the general population, an individual can only have two.
What is multiple allele gene expression?
Instead of having only two alleles for a trait, there are more than two. An example in humans is the ABO blood group system, where there are three alleles that are possible. However, an individual can only inherit the alleles of his/her parents, for a total of two alleles.
What are the characteristic of multiple alleles?
1) Multiple alleles are always on the same location (locus) on the alleles.2)they always effect the same character.3)They always occupy the same gene locus on chromosome.4)no crossing over is known to occur on chromosome.5)a single multiple allelic series affects only one trait _eye color etc
